I applied for a vacancy via LinkedIn. A few weeks later I received a mail to schedule an appropriate date for having a phone interview, which was confirmed. So far, so good. However, 30 minutes before the call, I got a mail to reschedule the call to a later moment that day. I agreed, but never got the call. After sending a reminder, a new moment was scheduled. However, again - cancelled and rescheduled. Haven't heard from them since, although I tried to contact the recruiter as she again didn't call me. Not quite impressed by professionalism.
